In a related matter, if I backed up all the CAFD files before doing any coding, am I able to restore those CAFD files and therefore bring my car back to factory settings?

If yes, what is the process of restoring the backup CAFD files?

Thanks.

When you right click on any CAFD file and select Read Coding Data, it reads the "as coded" data from the ECU, and saves it as an .ncd (net coding data) file.

So to restore that data or ECU state, in place of selecting Read Coding Data, select New and point to the saved .ncd file with the corresponding CAFD name in your backup folder and proceed with the regular steps of saving and activating FA and FDL Code the ECU.
